Heart Failure Duration Combined with Left Atrial Dimension Predicts Super-Response and Long-Term Prognosis in Patients with Cardiac Resynchronization Therapy Implantation

Table 3

Area under the curve and sensitivity and specificity for HF duration, LAD, and combination of HF duration and LAD.

Variables	AUC	95% CI	P for AUC	Cut-off value	Sensitivity; (%)	Specificity; (%)
HF duration (months)	0.789	0.67-0.91	< 0.001	≤ 36	88	70
LAD (mm)	0.775	0.67-0.88	< 0.001	≤ 42	82	71
Combination of HF duration and LAD (months, mm)	0.899	0.83-0.98	< 0.001	≤ 48 and ≤ 42	88	79

HF: heart failure; LAD: left atrial dimension; AUC: the area under the curve; 95% CI: 95% confidence interval.
